Back from GR8Conf EU. Great time and a lot of interesting material. I am myself quite a dev-ops newbie. However, I found the dev-ops day as a nice addition to the conference. The rest of the conference (coffee, beer, food, venue) was flawless. Kudos to @sbglasius and the rest of crew for putting together such a great show.

Groovy

We are community of awesome Latvian software craftsmen. Each month we host an event where we invite amazing speakers from across the world.

In his talk at GR8Conf EU, he shows how they have built a ChatBot called Craftbot which get deployed to AWS Lambda and AWS API Gateway. It takes commands from Slack, and it allows them to automate task such as event image uploading, email campaigns delivery, etc.

Grails

CodeNarc helps you code better. If you are working on a team, you can create and/or agree on rules which shape your team's coding style.

This week Grails guide shows you how to setup CodeNarc in a Grails 3 app (easy thanks to Gradle) and how to create a custom CodeNarc rule in a Grails Multi-Project Build. Being able to write your own rules gives you a lot of possibilities. Back in Issue 27, I linked to many CodeNarc resources. One of those links showed an example of how to use CodeNarc to detect vulnerabilities and improve security.

Vaadin is a framework which helps you build single-page web UIs for JVM applications. I have worked in the past with similar frameworks such as ZK. You probably have worked with similar technologies too. Vaadin seems more polished than those technologies. I attended @maciejprzepiora talk at GR8Conf EU about Vaadin and Grails, and I am intrigued about both frameworks playing together.

He has created a Grails 3 profile which allows you to have both regular Grails 3 endpoints and Vaadin enpdoints.
